Episode notes
Prototype Born From Travel Risks
- Michael Altfield built the first Buskill prototype in 2017 after feeling vulnerable while traveling and working in public spaces.
- The design went viral in 2020 and led him to manufacture the cables after demand outstripped supply.
Prefer Safe Defaults Over Auto-Wipe
- Use the Buskill GUI on macOS or Windows to limit actions to locking the screen or shutting down, avoiding dangerous automatic wipes.
- On Linux you can script more powerful triggers, but intentionally raise the barrier for destructive actions.
Interdiction Is A Major Supply-Chain Threat
- Interdiction is a real, large-scale threat where adversaries tamper with devices in transit.
- Buskill supplies 3D-printable designs and onion-market options to mitigate interdiction risk.
